thor 2 way lcd alarm and remote starter

I had this remote starter installed in my 2007 f-150 at my local ford dealer.It seems to go through all the motions but does no start the truck. Any ideas???

you should get more specific on what happens when you push the button if you expect some sort of help.

Let them fix it.  They installed it, they should fix it.  For education purposes you would first see whats happeing when it tries to start.  Does it crank but not turn over?  Does it even crank?  It could be a bypass issue but like I mentioned before, let them fix that problem with it because if you tamper with it they will right away void your warranty.

 I supplied the remote start for them.( i work for this dealership) They are not familiar with this unit . When  I push the button we got a negative pulse to the starter relay but starter doesn't crank. I will get the guy that installed the unit to give more details. soon
